Product Description:

Specifications: BVVB

Voltage levels: 300/500 v

Execution standard: JB/T8734-2012

Scope of application: this product is used ac rated voltage up to and including 450/750 (U0 / U) power, electrical appliances, instrumentation and telecommunications equipment.

Using features: 1, the cable of rated voltage U0 / U for 300/500 v. 2, long-term allowed working temperature does not exceed 70 ℃. More than 3, short circuit temperature: cable or multicore cable short circuit occurs (the longest duration of no more than 5 s), the highest temperature conductor does not exceed 160 ℃. 4, installing a wire laying, bending radius should be greater than the specified value. Diameter greater than 25 mm above the wires, bending radius should not less than 6 times of cable diameter. Diameter is less than 25 mm below the wire, bending radius should not less than 4 times of wire diameter. 5, PVC insulated and sheathed wire and cable laying, environment temperature should not be below 0 ℃. 6, plastic insulated wire such as BV cloth when installing laying wires, if wear pipe laying, should give full consideration to the diameter of the plastic pipe size, pipe threading the total cross section should be not more than 40% of the plastic tube hole section, for the normal operation of electric wire have plenty of room cooling, installation and wire laying should be far away from heat source.

Key performance indicators: 1, the conductor when 20 ℃ maximum dc resistance, 24.5 Ω/km. 2, the ac voltage 2500 v, 5 minutes not breakdown.

Q:How to connect the power cable pre-branch connector
Pre-branch cable detection: a In addition to routine pressure test, it is necessary to increase the insulation resistance test, with a shake table can be completed in each branch after the completion of injection The table measures the insulation in the finished product After the pressure is also used to detect the insulation of the table to prevent the water cooling process in the branch of the water caused by short-circuit, the general AC voltage test can not detect, can only increase a set of table detection process B Core conduction detection, In each branch body should be tested with the trunk of the conduction test to prevent the production process due to improper operation caused by the branch and the trunk circuit

The second category is the satellite receiving antenna, mainly the satellite antenna is not adjusted, according to the instructions to adjust the satellite receiver until the signal received. The third category is a cable digital TV, one is the cable line failure, resulting in no signal input, can consult the service phone; the other is the TV receiver unit failure, you can replace the TV try;
Q:Why does the sparrow stand on the wire without electric shock?
the network patch panel is now more mainstream network system patch panels, generally every 1U height can accommodate 24 8-core network port, back line, front jumper plug in addition, look at the Google Encyclopedia on the 110 patch panel instructions, found a little problem, that is 110 patch panel documents, but the picture is not 110 patch panels, that should be called Kelon, we also Called this thing for the VDF, it should be noted that the 110 system is AT & amp; T, that is, Lucent (Lucent) company's standards, and Kelon is the German Kelon (kelone) company's standard, not the same thing, Dragon frame is generally used in large-scale voice wiring system, and generally fixed for the wall, if placed in the standard cabinet will have to install the backplane, the Kelon frame steel frame fixed on the backplane The 110 patch panel is a standard 19-inch equipment, can be directly fixed in the standard 19-inch cabinet As the 19-inch standard cabinet has been widely used in the civilian areas, so Kelon is now less application, mainly in the use of operators these with a number of tattoo and fat ancient mix of full-chip cable is integrated wiring system in the most basic connector, the product range is also very much on the market, of course, there are many changes in the form On the use of network patch panels and 110 patch panels, Google Encyclopedia and the library have a detailed description, you can refer to
